Investigating the Association between IL-27 and Susceptibility to Preeclampsia among Iranian Women by Azam Aramesh, Bahia N. Jahromi, Morteza Samadi, Behrouz Gharesi-Fard

Background: Preeclampsia (PE) is one of the most serious disorders of human pregnancy with a high rate of mortality for the fetus and mother. Several etiological factors are involved in the onset of this disease. Upregulation of IL-27 has been reported in placental tissue recovered from preeclamptic women, but the role of IL-27 has not yet been investigated in PE. The aim of the study was to investigate the association of IL-27 rs153109 and rs17855750 gene polymorphisms with PE; also, protein levels and susceptibility and severity of PE in Iranian women were evaluated.
Methods: This case-control study was performed on 199 PE patients and 228 healthy women as the control group. IL-27 rs153109 and rs17855750 SNPs were genotyped using a PCR-RFLP method. Moreover, the levels of IL-27 were determined in 40 PE and 45 healthy women using ELISA method.
Results: Statistical analysis indicated that there were no differences in genotype, allele and genotype combination frequencies in the SNPs between cases and controls. The plasma level of IL-27 was elevated in the mild form of the disease compared with controls (p-value: 0.006).
Conclusions: The effect of IL-27 in preeclampsia is not due to the studied cytokine polymorphisms, but the level of IL-27 might be associated with the severity of preeclampsia in Iranian women.
